Jf'rILl-EGTTLE SAFE.

Application filed February l0, 1923.' Serial No. 618,373.

My invention relates to improvements inl milk bottle containers.) and it consists oi" 'the constructions. combinations and inode of operation herein described and claimed.

:in object of the invention is to provide a milk 'bottle container in the nature or a sale which embodies provisions not only insI o the tiert o'i iull milk bottles t, c lint also maires it necessary to set ont an empty bottle before the full bottle may he laken trom the container. Y

'further object ot the invention is to prei .do a milk bottle safe which primarily has two compartments and lockingmeans which so control the doors oit the compartments that it becomes necessary for the housewife to place an empty bottle in one oil the con'ipartinents helforc the 'full bottle may he tal-ren `from the other compartment, and on the other hand, makes it necessary iol; the milkman to place a 'iull bottle in the last named compartment betere he can Open the door to the other compartment and takeV the aforesaid empty bottle.

lOther objects and advantages will appear in the oll Wing' specilieation7 reference heing had to the accompanying drawings, in which:

l is a perspective view illustrating the general aspect ol? the improved milk hot ile salie9 ine 2-2 oit Fig. l,

bottle safe heine view-ei" 'trom a position corresponding to that in i.

g. 3 an inverted plan view oit the se. te,

ln carrying out the invention, provision is made of a cabinet l which has a top 2 and licor 3 27 land 5). The hack e and front extend down from the top 2 until they meet a fiance 6. The sides 7, however, e... end down from the floor 3 only (Figs. 2 and 4;), this arrangement defining a space invvhich the milk bottles are to oe placed.

il partition 8 divides this space into tivo compartments 9 and l0 (Figs. 4 and 5) which are repeatedly referred to below as the empty and iull milk bottle compart ments, respectively, The ends ot the compartments 9 and l0 are adapted to be closed by doors 1l, 'l2 and 13, 14e.

These doors work in pairs, that is to say, they are adapted either to lloe locked together or adapted to he opened together. rlhis may he illustrated hy an example in advance oi the description ot the mechaism.. the understanding oiz Which'will make this eatureolearer. Unless the housewife puts an empty hottie into the compartment 9, the pair of doors 13 and 14: Will remain locked so that access to compartment 10 cannot be had.

Placing an empty hottie into the compartment 9 will unlock the doors 13 and il sothat either one or the other, 0r looth, may he opened to gain access to the compartment l0. Upon placing milk bottle in the compartment 9, and permitting both doors l1 `and l2 to close, a locking,` of these doors will he effected.` The milkman cannot open yeither door il or l2 unless he places a r'ull bottle in the compartment l0. U

rie can then open either one or theother of doors 1l and l2 to getti/ie empty milk bottle. The doors l?) and i4.- vvill not become locked unless he takes the empty milk bottle ont. Upon taking the empty milk hottie out,hoth doors i3 and l'hecoine locked until the housewife again placesan emr/tv lmilk bottle in the compartment 9, whereupon both doors i3 and 14 eccome unlocked so that the full bottle can e taken out.. i

This advance description makes it plain to the reader that the two pairs of doors operate together, and this being so,.it is equally clear that there is merely a duplicate arrangement or the doors so that access to the cabinet may be had from one side or the other. A flange extending ug from 'the back 4, provides a convenient means lor fastening the cabinet to any suitable support. The ilange 6, referred to above, ex* tends completely around the cabinet.

A bottom 16 is slid in place on opposite flanges, for instance. those on the back l and front The corresponding edges ot the bottom are curled over so as to torni guides admitting these flanges. rlhe bottom has a ring 17 by which the bottom can be moved in place or removed when desired, lie bottom also includes a lug` 18 ac. tod to register with a corresponding lug 19 on t side 7 nearest to the observer in 1, so that a lock 20 may be applied to keep the bottom 1G in place and prevent meddling with the locking mechanism. Thisl mechanism is situated in a lock chamber 2l (Eig 2, 3 and d) which is defined by the, Vfloor o, bottom 16 and the various sides ci? the cabinet 1.

The various doors are hinged at 22 on the back and liront Walls and 5, and for the purpose of opening' the doors, each is provided With a knob 23. rl`he locking means includes springs by which the doors are closed. rlhese are speciiically referred to in the description of the locking mechanism below, but in addition to these springs, other springs 211 (Fig. 2) are employed in connection With each door to assist in closing. These springs are located at the top so as to equalize the closing effort.

.Sets or" indicators 25 and 26 are situated on the front Wall 5. These indicators are in the nature of metallic flags which in Ipractice have legends designating various quantities of milk or cream desired. All of this is readily understood from Fig'. 1. Since the various flags are mounted on a common pivot, any `desired one may be moved to the erect position.

Consider now the locking mechanism. A platform 2T in the compartment 9 is pivotally mounted at one side on a rod 28. The rod 23 is supported in the opposite portions of a flange 29 which depend `from the floor 3 and bounds the oliening 30 (Fig. in which the platform 27 operates.

The Weight ot a milk bottle (empty in this case) on the platform 2? in the compartment 9, causes the Weight lock rod 31 to rock so that the bolts 32 and are Withdrawn from the keepers and of the doors 13 and 1v1 ivhich close the compartment Y10. rlhis rocking oil 'the rod 31 is accomplished by a crank 36. A. spring 37, which has connection -with a crank 33 in the lock rod, keeps the crank 3G in contact With `the platform 27 and tends to move the bolts 32 and 33 upward.

Connected to the doors 11 and 12 at 39 and s0, (Figs. 3 and 5) are springs 1-1 which ifieeaes converge to a common point o connection at a crank fl-2 of a door-operated lock rod This lock rod terminates in bolts le and 15 which (with the bolts 32 and are also adapted to enter the keepers 3s and 35 of the doors 13 and 1d.

The closure of the doors 11 and 12 permits a spring L16 to rock the door-operated lock rod d3 through the medium or' the crank 12 in such. a direction as to retract the bolts el and 45 from the keepers 34 and 35. Should either the door 11 or 12 be in the open position, the crank i2 would be moved in the opposite direction through the medium of one or the other oiz the .spri gs Ll1 aml thereby move both bolts and 115 into engagement with said keepers. ln order to permit opening either door or 1d, it is necessary for the housewife to set a milk bottle upon the platform 27 in the compartment 9, thereby causing the Weight lock rod 31 and the bolts 32 and to rock downward and release said doors 13 and 11 tor opening.

However, et'ore -this can be done, the doors 11 and 12 must be closed upon the milk bottle new in the compartment 9 in order that the bolts el and 15 also may be retracted from engagement With the keepers and 35. is. similar lock arrangement obtains in respect to the compartment 10. i3. platforms?, situated in this compartment, .is pivotally mounted at one side on a rod d8. This rod is supported on opposite side members of a flange 49 which is bent downwardly from an opening 50 in the door .31.. spring` 51 (corresponding to the spring' has connection With a crank 52 in a weight lock rod 53, this spring keeping a crank 5st. in contact With the platform 4.97 and also tending' to keep bolts and 56 in engagement With keepers 57 and 58 on the doors 11 and 12.

Connected at 59 and GO (Figs. 3 and 5) to the doors 13 and 14;, are springs 51 which converge to a common point oit connection at the crank 62 ol.I a door-operated lock rod 63 on the opposite side` of the cabinet. 1n this connection it is to be 'noted that the doors (13 and 1s; for example) or" one compartment, are. adapted to actuate the dooroperated lock rod which is situated under the other compartment, and which is adapted to lock the doors of said other compartment. @n the same principle, the platform (47 lor enample) or 'one compartmentis adapted to actuate the Weight lock rod (53 for example) which controls 'the locking bolt o1 the doors of the other compartment. Referring again to the door-operated lock rod G3, this. at the extremities. has bolts 64 and 65 which also are adailoted 'to engage the keepers 57 and ot the doors 11. and 12. rihe opening oi"- oith door 13 or 1d Will .cause a pull on either spring wi m) i. ,esaltati 61 so that the bolts 64tand 65 are made to engage the aforesaid keepers. This act is contrary to the tension of a spring 66 which also has connection with the crank 62. The closing',` ot' either door 13 and 'le permits the spring' 66 to retract the bolts and 66 from the aforesaid keepers so that the doors 1l. and l2 are free to open in so far as the locking function ot the doors 13 and lll is concerned. 1t is necessary to a mill;

this instance) on the platorni A17 before the holts 55 and 56 will he retracted troni the keepers 57 and 5S and thereby permit the opening or" the doors 1l and l2.

ll/loyernent ot the Various lool; holte is limited hy suitable stops. rllhe door-op crated holte and 65 inove between lugs 67 and 68 il). The movement of the weight loch bolts 32, 33 and 55, is limited by lugs The door-operate=;:l lock bolts ed and e5 inoye between lugs 7l) and 71. fill of the Various lugs project into the lock chamber 21 from the side Walls 7.

The side Walls 7 also have slots 72 5) through which the various converging; springs -l-l and 61 pass when the respective doors to which theyT are attached are opened. Provision is made oi? hearings 73 and 7e bottle (full in vfor the support ont the various lock rods Si.

63 and 43, 58 (Fig. rllhesey bearings may consist o'l' depending sheet metal brackets fastened underneath ot the' lloor 3, and at the places Where these rods pass the pe ripheral 'flanges 29 and 49 at the platforms 27 and e7. adjacent portions of these flanges are merely n ade deeper to constitute hracln ets in which the rods have supports. T his is illustrated in the instance of the hearing 7st in e. rl`liis View also shows the use of a yoke 75 which is carried by the platforms and embraces the adjacent weight lock rods 31 and 53 to limit the lifting; increment ot each platform on the associated pivot rod.

The operation may he r Viewed in connecti n with the foregoing description. and thereby possibly bring out features which are not made entirely clear. rl`he conipartnient 9 is for empty milk bottles and the compartinent l() is iior 'lull niillr bottles. rlhe tiltable platforms 27 and 47 in these respective corhpartnients may7 with very little inodilication.l be made to entend the full lenvth of the respective compartments inst of oceupyinnn approximately only onehal.. the length. This inodftication would have the advantage of insuring the tilting; of the Anlatlorfu upon puttii'igia milk bottle into thesafe.

Assi-une that the housewife places an empty bottle into the compartment 9. 1u deine: this. care inust be teiten to set the z upon the platform 27. rlhe housecannot help hut do this. especially who; tiro 'empty quart nulli bottles are put into the compartment 9. yThe doors 11 and 12 are now closed. That is to say, one or the other of doors 11 and 12 is permitted to close because it is iinprobahlc that the houseu'i'fe would open both doors in order to set an oni-pty n'nllt bottle into the compart- Anent 9. v

The springs (figs. 5, le and 5) and 2l (Fig. 2) cause th i closing of the aforesaid doors. l'-.s v these doors are closed they spring latch.

Assume next that the millnian comes along'. lle niay attempt to open either door 11 or l?, to talte the einpt-y millt bottles. hut is prevented troni doing this because of the :tact vthat they are loclieda as just explained. lilou/rever, he niay open either door 13 or because if is intended that he should do so in order to out the full bottle of inillt into the compartment 10. hl either Y ydoor 13 nor 11iloelted `when there is an empty bottle in t ie compartment 9 and when both doors l1 and 1Q are closed. rlie Weight of the bottle on the pl..;;t`ori; '97 rocks the weight loci; rod 31 by virtue of the cranlr 36 so that the bolts 32 and 33 are retracted from the keepers Se and 35 of the doors 13 and 14. rlhe closing` ol the doors 11 and 12 permits the spring 46 to pull haelt on the crank ft2 and retract the door-operated loclr bolts et and /l JErorn the keepers 34 and Now h ving access to the coninarnnent 10, the roilhnan places a 4full hoitle on the platform 47. rlhis roclrs the Weightl loch rod by yirtue of the crank 54 so that the bolts 55 and 56 are retracted. from the keepers 57 and 58. Although this one locking; means is thus rendered inoperative, the doors 11 and 12 are, nevertheless, still locked. `This is so because it is assumed that the milknian is still holding one or the other of the doors 13 and 14.- open. This act causes a pull on one or the other of the sprinos 6l, a forward rocking of the cra-nk 62 on. the door-operated loch rod 63 so that the holte 6l and 66 are moved up into the keepers 57 and 58 in Vpla-ce of the bolts 55 and 56, as aforesaid.

ln. order that the Inillnnan loe permitted to fet the empty millt bottle from the compartinent 9. he must close both doors 13 and 14. This relaxes the spring 61, permits the spring 66 to' pull the look rod 63 haelt and thus relli tracts the bolts 6l and 65. There is non a full milk bottle on the platform 47 and the bolts 55 and 56 stand retracted. Either door ll or 12 may now be opened and the milk bottle taken out. 'lhe removal of the weight from the platform 27 permits the locking bolts 32 and 33 to spring up into engagement with the keepers Sil and so that the full bottle of milk in the compartment l0 is safe 'from anyone who might irish to take it.

Even the housewife cannot get' the full bottle of milk unless she opens one or the other of the doors ll and l2 and places another empty milk bottle ou the plat-form 27. She is next compelled to close the doors to the compartment 9 so as to retract the bolts 4st and l5 from the respective keepers, the bolts 32 and 83 having been retracted by the act of placing the bottle on the platform 27. Either door 13 or l-l can nosv be opened to take the full milk bottle, but the doors ll and l2 are again loc`I ed by the attendant release of Weight from the platform lr so that the empty milk bottle cannot be retaken from the compartment 9.

One of the advantages of this milk safe is that the housewife will always have her milk bottle out, that is to say, the full milk bottle cannot be obtained unless an empty bottle is placed into the safe for the next days supply, Another advantage of the milk safe is that the stealingof both full and empty milk bottles is safeguarced against. Furthermore, stray animals are prevented from getting the milk bottles, this often being` the case When milk bottles are left exposed on door steps, etc.

lVhile the construction and arrangement of the improved milk bottle safe as herein described and claimed is that of a generally preferred form, obviously inodications and changes may be made Without departing from the spirit of the invention or the scope of the claims.
